Please note that a ALL of these Handouts and the Exercises (SHOWN AS 'EXERCISE' BELOW) are *.pdf files. When you click on a Handout OR Exercise it is likely that it will appear in your ADOBE ACROBAT READER SOFTWARE (if you have it) and will PROMPT you for a PASSWORD.

ALL UPDATED TO MATCH BS7671:2008

_{Notes for Lecturers - Exercises are differentiated to allow more advanced students to be 'pushed' further. There are Standard questions, ADVANCED questions and Further ADVANCED questions. This follows the 'all students will be able to', 'most students will be able to', and 'some students will be able to' differentiation strategy encouraged by OFSTED.}

YOU WILL HAVE TO USE A PASSWORD TO OPEN THE HANDOUT PAGES - PLEASE DO NOT ATTEMPT TO DOWNLOAD WITHOUT A PASSWORD. YOU WILL NOT BE ABLE TO ACCESS THEM AND WILL WASTE BANDWIDTH!
